  • the parallax barrier method is disclosed in S.H. Kaplan, "Theory of Parallax Barriers", J. SMPTE, Vol. 59, No. 7, pp. 11 - 21 (1952). With this method, a stripe image formed by at least alternately arranging right and left image portions obtained from a plurality of parallax images picked up at a plurality of view points is observed via a slit (called a parallax barrier) having predetermined aperture portions as parallax images corresponding to the two eyes of an observer, thus attaining stereoscopic viewing.

  • the display operation of the parallax barrier on the electronic parallax barrier 103 is stopped, so that the entire image display area is set in the transparent state, thereby realizing compatibility with a two-dimensional image display apparatus unlike in a conventional stereoscopic image display apparatus using the parallax barrier method.

  • the width, A, of each light-shielding portion can be set to be equal to the width, B, of each light-transmitting portion.

  • Fig. 18 is a graph showing the relationship between the number of view points and the luminance/resolution in the stereoscopic image display apparatus using the parallax barrier method.
  • the screen luminance upon displaying a three-dimensional image lowers as the number of view points increases, as shown in Fig. 18. More specifically, when the three-dimensional image is a stripe image obtained by synthesizing parallax images obtained from two view points, the screen luminance becomes 0.6; when the three-dimensional image is a stripe image obtained by synthesizing parallax images obtained from three view points, the screen luminance becomes as dark as about 0.4.

    a) la plage de valeurs de luminance d'une image partielle sur ledit moyen (1) d'affichage d'image ;
    b) si le moyen de parallaxe partielle est un panneau de modulation de lumière en parallaxe partielle (2) disposé entre le moyen d'affichage d'image et ladite position prédéterminée, le pouvoir de transmission des parties transmettrices de lumière correspondant à une image partielle dans le panneau de modulation de lumière.
  14. Appareil selon la revendication 13, comprenant en outre un moyen (2, 25) de commande de parallaxe partielle pour modifier une configuration de la barrière en parallaxe partielle en correspondance avec le nombre de points d'observation de l'image partielle.
  15. Appareil selon la revendication 13 ou 14, comprenant en outre un moyen (3) d'éclairage pour éclairer ledit moyen (1) d'affichage d'image.
  16. Appareil selon la revendication 15, dans lequel ledit moyen d'affichage d'image comprend un panneau (1) de modulation de lumière d'affichage d'image.
  17. Appareil selon la revendication 15 ou 16, dans lequel ledit moyen d'éclairage comprend une surface d'éclairage divisée en une pluralité de zones divisées (31i, j) et ledit moyen (6) de commande de lumière est agencé pour régler la quantité de lumière émise par au moins l'une de ladite pluralité de zones divisées.
  18. Appareil selon la revendication 17, dans lequel ledit moyen (1) d'affichage d'image et ledit moyen (2) de parallaxe partielle sont respectivement agencés pour obtenir des lignes limites des images partielles et des lignes limites de la barrière en parallaxe, qui sont superposées à des lignes de division desdites zones divisées de ladite surface d'éclairage.
  19. Appareil selon l'une quelconque des revendications 15 à 18, dans lequel ledit moyen (6) de commande de lumière est agencé pour commander l'éclairage dudit moyen (1) d'affichage d'image par ledit moyen (3) d'éclairage pour commander la plage de valeurs de luminance d'une image partielle sur ledit moyen d'affichage d'image.
  20. Appareil selon la revendication 13 ou 14, dans lequel ledit moyen d'affichage d'image comprend un élément d'affichage du type à auto-émission, et ledit moyen (15) de commande de lumière est agencé pour commander une valeur de luminance dudit élément d'affichage du type à auto-émission.
  21. Appareil selon la revendication 13 ou 14, dans lequel ledit moyen de parallaxe partielle comprend un visuel (25) du type à auto-émission ayant des parties émettrices de lumière, et ledit moyen de commande de lumière est agencé pour commander une valeur de luminance desdites parties émettrices de lumière.
  22. Appareil selon l'une quelconque des revendications 13 à 21, dans lequel ledit moyen (6, 15, 16) de commande de lumière est agencé pour établir les niveaux de brillance des images partielles pour qu'ils soient sensiblement égaux les uns aux autres.
  23. Appareil selon la revendication 22, dans lequel ledit moyen (6, 15, 16) de commande de lumière est agencé pour maintenir les niveaux de brillance des images partielles pour qu'ils soient sensiblement constants lorsque le nombre de points d'observation d'une image à afficher, varie.
